Start by completing the square.

x^2-8x-3y^2+12y=-16
x^2-8x+16-3(y^2-4y+4)=-16+16-12=-12

Notice the addition of those constants allows us to factor these expressions and because we did it to both sides it’s completely legit.

(x-4)^2-3(y-2)^2=-12

However, it seems we get a negative radius, which is not allowed. I think you entered the problem incorrectly.

Hi another math question please help:)
Mama L [17]

Answer:

1). Yes

2). Yes

3). No

Step-by-step explanation:

1). y = 3

  We can rewrite this equation in the slope-intercept form as,

   y = 0.x + 3

  Here, slope = 0

  y-intercept = 3

  Therefore, it's a linear relation.

  YES.

2). 2x - 5y = 10

   5y = 2x - 10

   y = \frac{2}{5}x-2

   Therefor, it's a linear function.

   YES

3). y = x(x + 3)

   y =x² + 3x

   Since, this equation is a quadratic equation,

   It's not a linear function.

   NO
